Yes, it does, but not the way people think. it doesn't gain it from the weight of all the people. the earth takes mass from elsewhere, as our population continues to grow.
Th memory cells differ from the effector cells in that the memory cells live longer. Two types of cells are produced by the clonal selection, these are the effector cells and the memory cells. Effector cells are relatively short lived activated cells that defend the body in an immune response. Effector B cells are called plasma cells and secrete antibodies, and activated T cells include cytotoxic T cells and helper T cells, which carry out cell-mediated responses. The production of effector cells in response first time exposure to an antigen is called the primary immune response. The memory produced at this time and only become active in case of a re-exposure to the same antigen that stimulated their formation.
Proximal convoluted tubule cells. As well as the epithelial cells along the renal tubule and the duct. Hope this helps!:)
I think it’s C. There is a chance it could be B but I’m 99.9% sure that the correct answer is C.
Can you please mark this brainliest? I only need one more to rank up :)
When pelvic or long bone damaged, it can cause internal bleeding.
Internal bleeding is a loss of blood in a body cavity. It was dangerous as the bleeding is not visible, thus hard to be identified. Internal bleeding can happen when there is vascular damage part of the body with cavity like pelvis, or when long bone like femur fractured. Organs in abdomen like spleen and liver also at risk of internal bleeding.
